20 amp GFCI breaker pops when pool pump is turned on.
 
Hi,
Maybe someone can help me with this.

When I would turn my pool pump on the 20amp gfci breaker would pop. This happened to me twice before in the past due to a bad plug end and moisture where the wires hookup in the pump shorting out. I had no issues fixing that problem.

When I turned on my pump this morning, it kept popping. So I checked all the wiring again and it looks good. So what I did was remove the GFCI 20 amp breaker and replaced with a regular 20 breaker and it works fine.

Could it be that my GFCI breaker is bad or do I still have a fault somewhere in the line and canít tell because Iím using a regular 20 amp breaker? I didnít go out a get a new GFCI breaker yet to see if thatís the issue.

My guess is that the GFCI breaker could not handle the power when I would turn on the pump.


Along that circuit I have separate switches for a light and pool pump. If I would just turn on the light while the GFCI breaker was on I have no issues r but when I turn on the pool pump it pops.


Before I go out and get a new GFCI breaker, could it be a bad breaker. I had for about 10 pool seasons. Is there a way to test this GFCI breaker not on the panel?

Thank you,

Jamie

Bypass the GFCI and put a 7-1/2w incand. lamp in series with the ground wire that is downstream of the GFCI. More than 1v across the lamp due to current in the ground wire is a legitimate ground fault.

Yet it did OK for ten years. Hmmmmmm.
And the lights alone work fine. Hmmmmmmm.

I think you have a problem in the motor and should have it checked out. And PUT THE GFI BREAKER BACK IN!


Also, you should NOT have the lights on the pump circuit. Do you mean an underwater light? If so then I suspect more is wrong than you know. :whistling2:

X2 with Pete's comment.

If you have pump and in pool luminaire on the same circuit then you have very serious issue with code and maybe other thing need to be straighten out.

and yeah put the GFCI breaker back NEVER run the pump circuit without GFCI at all this is very important part !!!!

My pumps on 240v setup.....no GFCI at all :(
....now required under NEC 2008?

But it is on a dedicated circuit
Pool light ALWAYS on a GFCI circuit - NO EXCEPTION !!!

Seperate immediately & install another GFCI for the light
Put the GFCI back in for the pump

Dave .,

Unforetally.,

Yes the 240 volt pool pump have to be on GFCI on 2008 NEC code cycle.

I don't have the excat NEC number but I do recalled it was stated clear in 2008 NEC code. that came out not too long ago when the 2008 NEC code change show up.

Merci,Marc

I believe you're referring to 680.22(B)

And you're probably the type that put a penny behind your fuses when they blew and said "it works fine." :furious: I know I wouldn't let my kids in that pool!

Put a new GFCI back in, who cares if the old one is "good." A 20A GFCI will cost you $35 at Lowes, likely cheaper online, go order one NOW!

Oh, and fix the lighting issue now too!

I know this is a DIY site however I recommend you call a pro now.

Water and electric no no.

Just a recommendation that's all.

I build pools (I am not an electrician) but the GFCI outlet and light(s) of the pool are on the same circuit when we build pools. I do inground and the pumps we use are 240V on their own circuit, but it is proper to have the light(s) on the GFCI outlet circuit as it provides GFCI protection to the light(s). If there was a problem with the light it would trip the GFCI when the light was turned on.

I would suspect the pump has a fault in it somewhere. You should be able to uncover the plug connection to the pump and see if something is amiss in there, like water on a spade connector. More than likely the pump internally has an issue and needs to be replaced.

That said, after years of use a GFCI can go bad. The circuitry is very sensitive. I have seen this on hot tubs more than once, where the GFCI keeps tripping and after hours of diagnosis we find the GFCI has just gone bad.

First thing is to purchase a new GFCI outlet and install it.

I have to say, this is NOT exactly true.
It is sometimes acceptable with have the lights on with a receptacle circuit, but it is NOT mandatory, required or proper.
Yes, pool lights require GFI protection, but this is not the only way.
